실험 절차

Sodium (3.5 g, 0.15 mol) was added to methanol (150 mL) carefully. After cooling to room temperature, methyl 2-mercaptoacetate (15.6 g, 0.13 mol) was added. The mixture was stirred for 30 mins at room temperature and a little of NaI and methyl 4-chlorobutanoate 20.0 g, 0.15 mol) were added. The reaction mixture was refluxed over night. After cooling to room temperature, the solvent was removed under reduced pressure, then the residue was dissolved in CH2Cl2 (100 mL). The solution was washed with H2O (30 mL), brine (30 mL), and dried with Na2SO4. After removing the solvent, 28.3 g of the crude product was obtained (Yield: 94%).
